STK17T88

32K x 8 AutoStore nvSRAM with Real-Time Clock

FEATURES

DESCRIPTION

• nvSRAM Combined With Integrated Real-Time

Clock Functions (RTC, Watchdog Timer, Clock

Alarm, Power Monitor)

The Simtek STK17T88 combines a 256Kb non-vola-

tile static RAM (nvSRAM) with a full-featured real-

time clock in a reliable, monolithic integrated circuit.

The 256Kbit nvSRAM is a fast static RAM with a

non-volatile Quantum Trap storage element

included with each memory cell.

• Capacitor or Battery Backup for RTC

• 25, 45 ns Read Access & R/W Cycle Time

• Unlimited Read/Write Endurance

The SRAM provides the fast access & cycle times,

ease of use and unlimited read & write endurance of

a normal SRAM. Data transfers automatically to the

non-volatile storage cells when power loss is

detected (the STORE operation). On power up, data

is automatically restored to the SRAM (the RECALL

operation). Both STORE and RECALL operations

are also available under software control.

• Automatic Non-volatile STORE on Power Loss

• Non-Volatile STORE Under Hardware or Soft-

ware Control

• Automatic RECALL to SRAM on Power Up

• Unlimited RECALL Cycles

• 200K STORE Cycles

The real time clock function provides an accurate

clock with leap year tracking and a programmable,

high accuracy oscillator. The Alarm function is pro-

grammable for one-time alarms or periodic minutes,

hours, or days alarms. There is also a programma-

ble watchdog timer for processor control.

• 20-Year Non-volatile Data Retention

• Single 3 V +20%, -10% Power Supply

• Commercial and Industrial Temperatures

• 48-pin 300-mil SSOP Package (RoHS-

Compliant)
